Again I would caution you about quoting the Rifleman article to much there was more than one mis-print and some information got into the wrong columns. The mag pellets are considerably more powder thanthe the regular 50 grain T7pellet which is the equivelant of BP or Pyros. The regular pellets are approximately 36 grains (by volume) of regular T7-2f.
There have been plenty of recorded comparisons on this forum that validate the velocity difference between the pryos and T7, especially when it comes to pressure developed in the barrel.
Not everything in print is actually right for all...
